These crushers are widely used in the construction industry, mining field, highway construction, water conservancy and hydropower engineering, and environmental protection fields.

[0003] As disclosed in publication number CN209222202U, a building stone crusher controls the operation of a motor through a controller, so that the first shaft drives the crushing roller to crush the material, and the pump body is connected to the nozzle through a water pipe, so that the nozzle generates water mist to precipitate the dust generated on the lower side of the feed port, and then the first shaft is connected to the second shaft through a transmission belt, and the second shaft is meshed with the middle part of the meshing transmission planetary gear plate for transmission, and a plurality of steel rods are installed on the pinion on the planetary gear plate, so that the steel rods rotate under the drive of the planetary gear plate, and the material falling after crushing is evenly stirred, so that the material falls evenly and disperses, reducing accumulation, making full use of the carrying space of the loading bucket truck, and the material is relatively not easy to spill.

[0004] This patent allows the falling materials to be dispersed evenly, reducing accumulation and making full use of the carrying space of the loading bucket truck. The materials are relatively less likely to spill. However, the existing crushers require operators to pour construction materials into the feed port for crushing during loading. The feed port is relatively high, which is very inconvenient during loading, and the manual loading efficiency is low. Therefore, we propose a new type of construction material crusher.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a building material crusher, including a crusher body, the front surface of the crusher body is connected to an automatic loading assembly, the automatic loading assembly includes a main bracket, a one-way screw is arranged inside the main bracket, a bearing is arranged at the top of the one-way screw, the bottom end of the one-way screw is connected to the output end of a first motor, the bottom of the bracket is connected to a supporting leg, a lifting block is arranged on the surface of the one-way screw, a threaded hole is opened inside the lifting block, the front surface of the lifting block is connected to a lifting platform, the bottom of the lifting platform is connected to a support rod, a side surface of the lifting platform is connected to a second motor, the output end of the second motor is fixedly connected to a rotating rod, and the surface of the rotating rod is connected to a loading box.

[0007] Furthermore, the first motor is electrically connected to an external power source via a control switch, and an output end of the first motor passes through the main bracket and is fixedly connected to the one-way screw bracket.

[0008] Furthermore, the one-way screw is rotationally connected to the main bracket and the bearing, and the one-way screw is threadedly connected to the lifting block through the threaded hole.

[0009] Furthermore, the outer surfaces on both sides of the lifting block are in contact with the inner walls on both sides of the main bracket, and the supporting legs are in a "U" shape.

[0010] Furthermore, the rotating rod and the loading box are fixedly connected.

[0011] Furthermore, a protective component is connected to the top of the crusher body, and the protective component includes a feed port, and a hinge is connected to a side surface of the feed port.

[0012] Furthermore, a cover plate is connected to one side of the hinge, and the position and size of the cover plate match the position and size of the feed port.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the building materials need to be crushed, the materials can be poured into the loading box first, and then the first motor is turned on to drive the one-way screw to rotate, so that the lifting platform drives the loading box to rise through the rotation of the thread, and then the second motor is turned on to pour the materials in the loading box into the feed port, thus completing the automatic loading, avoiding the time-consuming and labor-intensive problem of existing manual loading, and improving the crushing efficiency of the crusher body.
